Liam Hemsworth's Street Fight Caught on Video

Miley's man may have some anger management issues.

Liam Hemsworth was involved in a violent brawl outside a Philadelphia bar on Wednesday Dec. 12, with video documenting the incident at PerezHilton.

Witness tell the site that the Hunger Games actor, 22, was departing the bar when he apparently spied a drunk man supposedly throwing rocks at him and his friend.

Angered, the Australian star and his friend punched the man as his friend held him down on the street. As shown in the video, policeman quickly showed up on the scene. No arrests have yet been made in the altercation.

Back in September, Hemsworth and fiancee Miley Cyrus were named in a supposed tussle at Hollywood hotspot Beecher's Madhouse -- with Cyrus, 20, allegedly breaking up her husband-to-be's argument with another clubgoer. "This is completely false and erroneous," Cyrus' rep said at the time.
